一、效果
原图：
转换后：
效果可通过代码开头几行的参数调节
二、代码
开头几行代码，自己看着调整，把效果调到最佳就ok。
依赖库：
pip install opencv-python
pip install pygame
代码：
import pygame
import cv2
FONT_SIZE = 18 # 字体大小，可自行调整
WIN_SIZE = (1440, 1000) # 窗口大小，可自行调整
VIDEO_SIZE = (30, 30) # 视频大小，可自行调整
VIDEO_PATH = './cat.gif' # 视频文件（可以为常见的视频格式和gif）
STR_TEXT = '假装失智' # 替换字符，可自定义，没有长度限制，但至少得有一个
def video2imgs(video_name, size):
img_list = []
cap = cv2.VideoCapture(video_name)
while cap.isOpened():
ret, frame = cap.read()
if ret:
img = cv2.resize(frame, size, interpolation=cv2.INTER_AREA)
img_list.append(img)
else:
break
cap.release()
return img_list

winSur.fill((0, 0, 0))
winSur.blit(sur_list[current_frame], [0, 0])
current_frame += 1
current_frame %= len(sur_list)
# 刷新界面
